【PHP】PHP实现二维数组转一维数组 可以使用 array_reduce() 函数将二维数组转换为一维数组。array_reduce() 函数将通过一个回调函数迭代数组中的所有值，并将它们合并为一个单一的值。在这种情况下，我们将使用 array_merge() 函数将所有子数组合并为一个单一的数组。示例代码如下：function flatten_array($arr) { return array_reduce($arr, function($carry, $item) { return array_merge($carry, is_array($item) ? flatten_array($item) : array($item)); }, array()); } // 测试 $arr = array( array(1, 2, 3), array(4, 5, 6), array( array(7, 8), 9, array(10, 11, 12), ), ); $result = flatten_array($arr); print_r($result); // 输出： // Array // ( // [0] => 1 // [1] => 2 // [2] => 3 // [3] => 4 // [4] => 5 // [5] => 6 // [6] => 7 // [7] => 8 // [8] => 9 // [9] => 10 // [10] => 11 // [11] => 12 // )在上面的示例代码中，我们定义了一个 flatten_array() 函数，该函数使用 array_reduce() 函数和递归调用来将二维数组转换为一维数组。

【PHP】php.ini如何配置，才是PHP性能最大优化？ 内存 默认设置memory_limit = 128M单个进程可使用的内存最大值，这个值的设定可以从以下几点考虑：应用的类型。如果是内存集中型应用，可增加该值；单个 PHP 进程平均消耗的内存，该值可通过多次运行同一个脚本来计算平均值；能负担多少个 php-fpm 进程；该值等于分配的总内存除以单个 PHP 进程平均消耗的内存文件上传 默认设置file_uploads = On max_file_uploads = 20 upload_max_filesize = 2M max_execution_time = 30 值 为 0 代表没有限制设置max_file_uploads来决定同时允许多少个文件上传；设置upload_max_filesize来决定每个文件上传的最大值；如果是长时间任务，尽量使用队列来处理，因此，可适当缩短max_execution_time的值；注意， Web 服务器也可以设置文件上传大小及超时时间，不能仅仅以 php.ini 的设置为准；会话 PHP 的会话默认是保存在硬盘中session.save_handler = files在实际应用中，应当将会话保存在内存中。可使用 Memcached 或者 Redis。这样做主要有两个好处：提高速度；有助于后期的扩展，如果会话数据存储在硬盘中，不便于增加额外的服务器，如果把会话数据存放在 Memcached 或 Redis 里，任何一台分布式 PHP-FPM 服务器都能访问会话数据。可通过 PECL 安装memcached扩展并设置默认的save_handler为memcachedsession.save_handler = 'memcached' session.save_path = '127.0.0.1:11211'缓冲输出 默认值realpath_cache_size = 4M realpath_cache_ttl = 120PHP 会缓存应用使用的文件路径，这样每次包含或导入文件时就无需不断搜索包含路径了，这个缓存叫真实路径缓存（realpath cache），如果运行的是大型的 PHP 文件（如 Composer 组件），使用了大量文件，增加 PHP 真实路径缓存的大小能得到更好的性能。

【PHP】PHP实现协同推荐算法 概述：　　因为最近对算法这块进行了学习，所以最近对类似淘宝商品推荐的协同推荐算法进行了整理总结，本文将用php语言进行实现，文章将从以下几点进行终结：　　　　（1）什么是协同推荐算法？有什么用？　　（2）依据什么数学方法公式，为什么要用它？　　（3）实现流程是怎样的？　　（4）具体实现步骤。　　首先，第一点，我们要实现一个算法必须要知道它有什么用，核心思想是什么？顾名思义，它的用途就是用来给我们做一些相似性推荐，推荐你喜欢的恭喜，根据你的好友等预测你喜欢的然后再推荐给你；我们举个例子来概括一下算法的核心思想：该算法的核心思想可以概括为：若a,b喜欢同一系列的物品（暂时称b是a的邻居吧），则a很可能喜欢b喜欢的其他物品。算法的实现流程可以简单概括为：1.确定a有哪些邻居 2.通过邻居来预测a可能会喜欢哪种物品 3.将a可能喜欢的物品推荐给a。　　现在我们了解了这个核心思想以后，我们知道算法的核心是数学逻辑，我们必须理解其数学思想，然后再转化为编程思想达到我们的目标： 我们先回忆一下余弦定理：　 可见cosA的夹角越小cosA的值越大，则边c和边b的长度越相近，因此我们利用余弦定理的向量方式类推出如下公式：1.余弦相似度（求邻居）：2.预测公式（预测a可能会喜欢哪种物品）：　　接下来我们介绍一下实现流程：　　现在我们具体看看怎样用php实现这个算法：　　（1）数据准备：在这里我们直接定义一组数据$userarray= [ ['name'=>'A','a'=>3,'b'=>2,'c'=>1,'d'=>5,'e'=>null,'f'=>null,'g'=>null], ['name'=>'B','a'=>1,'b'=>6,'c'=>6,'d'=>5,'e'=>2,'f'=>3,'g'=>5], ['name'=>'C','a'=>3,'b'=>5,'c'=>null,'d'=>4,'e'=>3,'f'=>3,'g'=>6], ['name'=>'D','a'=>4,'b'=>1,'c'=>1,'d'=>5,'e'=>3,'f'=>3,'g'=>3], ['name'=>'E','a'=>5,'b'=>1,'c'=>null,'d'=>4,'e'=>5,'f'=>1,'g'=>5], ['name'=>'F','a'=>1,'b'=>3,'c'=>2,'d'=>5,'e'=>6,'f'=>null,'g'=>4], ['name'=>'G','a'=>1,'b'=>5,'c'=>2,'d'=>5,'e'=>2,'f'=>3ll,'g'=>5] ];　　(2)我们以A用户为对象分别计算出他们的余弦相似度，然后将其存入数组$cos中：/* * 以下示例只求A的推荐 */ $cos = []; $cos[0] = 0; $denominator_left = 0;//分母左边初始值 //开始计算cos //计算分母左边 for($i=1;$i<8;$i++){ if($userarray[0][$i] != null){//$userarray[0]代表A $denominator_left += $userarray[0][$i] * $userarray[0][$i]; } } $denominator_left = sqrt($denominator_left);//取算数平方根的值 for($i=1;$i<6;$i++){ $numerator = 0;//分子初始值 $denominator_right = 0;//分母右边初始值 for($j=1;$j<8;$j++){ //计算分子 if($userarray[0][$j] != null && $userarray[$i][$j] != null){ $numerator += $userarray[0][$j] * $userarray[$i][$j]; } //计算分母右边 if($userarray[$i][$j] != null){ $denominator_right += $userarray[$i][$j] * $userarray[$i][$j]; } } $denominator_right = sqrt($denominator_right ); $cos[$i]['cos'] = $numerator /$denominator_left /$denominator_right ;//存储当前用户的cos近似值 　　 $cos[$i]['name'] = $userarray[$i]['name'];//存储当前用户的名字 　　　$cos[$i]['e'] = $userarray[$i]['e'];//存储当前用户的e物品评分 　　　$cos[$i]['f'] = $userarray[$i]['f'];//存储当前用户的f物品评分 　　　$cos[$i]['g'] = $userarray[$i]['g'];//存储当前用户的g物品评分 }(3)我们对余弦近似值进行由大到小的排序，抽取前三个用户作为A用户的邻居，我们使用冒泡排序法对其进行排序// 第一层可以理解为从数组中键为0开始循环到最后一个 for ($i = 0; $i < count($cos) ; $i++) { 　　// 第二层为从$i+1的地方循环到数组最后 for ($j = $i+1; $j < count($cos); $j++) { 　　　　　// 比较数组中两个相邻值的大小 if ($cos[$i]['cos'] < $cos[$j]['cos']) { $tem = $cos[$i]; // 这里临时变量，存贮$i的值 $cos[$i] = $cos[$j]; // 第一次更换位置 $cos[$j] = $tem; // 完成位置互换 } } }　(4)接下来我们对A用户可能喜欢的物品进行预测，利用第二个公式，求出product值//计算A对e的评分 $numerator= 0;//分子初始值 $denominator= 0;//分母初始值 for($i=0;$i<3;$i++){ $numerator+= $cos[$i]['cos'] * $cos[$i]['e']; $denominator+= $cos[$i]['cos']; } $score_e = $numerator/sqrt($denominator); //计算A对f的评分 $numerator= 0;//分子初始值 $denominator= 0;//分母初始值 for($i=0;$i<3;$i++){ $numerator+= $cos[$i]['cos'] * $cos[$i]['f']; $denominator+= $cos[$i]['cos']; } $score_f= $numerator/sqrt($denominator); //计算A对g的评分 $numerator= 0;//分子初始值 $denominator= 0;//分母初始值 for($i=0;$i<3;$i++){ $numerator+= $cos[$i]['cos'] * $cos[$i]['g']; $denominator+= $cos[$i]['cos']; } $score_g= $numerator/sqrt($denominator);最后我们可以比较这些值，可以选取值最大的物品推荐给用户A

【PHP】PHP报错ssl3_get_server_certificate:certificate verify failed问题 getimagesize(): SSL operation failed with code 1. OpenSSL Error message:error14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed提示缺少证书，搜到很多帖子写的感觉不是很清楚，以下步骤我自己记录一下先下载cacert.pem证书, https://curl.se/ca/cacert.pem，下载完后我直接上传到了/www/server/php目录下找到对应的php版本的php.ini文件将openssl.cafile其路径替换为openssl.cafile=/www/server/php/cacert.pem也就是你刚把cacert.pem证书上传的路径最后重启php服务即可
